Examinations were made on the application of the method previously reported, for derivation of furoquinoline alkaloids by the reductive cyclization of the enol-methyl ether of α-(10-nitrobenzoyl)-γ-butyrolactone to the synthesis of 7-hydroxy-8-methoxydictamnine, the parent structure of evoxine and evoxoidine, and of 2, 3-dihydroskimianine, and a satisfactory result was obtained.
